Quick Start Guide

Get the Atlas voice agent system up and running quickly.

Prerequisites

  1. Python 3.8+ installed
  2. Ollama installed and running (for local testing)
  3. pip for installing dependencies

Setup (5 minutes)

1. Install Dependencies

cd /home/beast/Code/atlas/home-voice-agent/mcp-server
pip install -r requirements.txt

2. Configure Environment

cd /home/beast/Code/atlas/home-voice-agent

# Check current config
cat .env | grep OLLAMA

# Toggle between local/remote
./toggle_env.sh

Default: Local testing (localhost:11434, llama3:latest)

3. Start Ollama (if testing locally)

# Check if running
curl http://localhost:11434/api/tags

# If not running, start it:
ollama serve

# Pull a model (if needed)
ollama pull llama3:latest

4. Start MCP Server

cd /home/beast/Code/atlas/home-voice-agent/mcp-server
./run.sh

Server will start on http://localhost:8000

Quick Test

Test 1: Verify Server is Running

curl http://localhost:8000/health

Should return: {"status": "healthy", "tools": 22}

Test 2: Test a Tool

curl -X POST http://localhost:8000/mcp \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
      "name": "get_current_time",
      "arguments": {}
    }
  }'

Test 3: Test LLM Connection

cd /home/beast/Code/atlas/home-voice-agent/llm-servers/4080
python3 test_connection.py

Test 4: Run All Tests

cd /home/beast/Code/atlas/home-voice-agent
./test_all.sh

Access the Dashboard

  1. Start the MCP server (see above)
  2. Open browser: http://localhost:8000
  3. Explore:
    • Status overview
    • Recent conversations
    • Active timers
    • Tasks
    • Admin panel

Common Tasks

Switch Between Local/Remote

cd /home/beast/Code/atlas/home-voice-agent
./toggle_env.sh  # Toggles between local ↔ remote

View Current Configuration

cat .env | grep OLLAMA

Test Individual Components

# MCP Server tools
cd mcp-server && python3 test_mcp.py

# LLM Connection
cd llm-servers/4080 && python3 test_connection.py

# Router
cd routing && python3 test_router.py

# Memory
cd memory && python3 test_memory.py

View Logs

# LLM logs
tail -f data/logs/llm_*.log

# Or use dashboard
# http://localhost:8000 → Admin Panel → Log Browser

Troubleshooting

Port 8000 Already in Use

# Find and kill process
lsof -i:8000
pkill -f "uvicorn|mcp_server"

# Restart
cd mcp-server && ./run.sh

Ollama Not Connecting

# Check if running
curl http://localhost:11434/api/tags

# Check .env config
cat .env | grep OLLAMA_HOST

# Test connection
cd llm-servers/4080 && python3 test_connection.py

Tools Not Working

# Check tool registry
cd mcp-server
python3 -c "from tools.registry import ToolRegistry; r = ToolRegistry(); print(f'Tools: {len(r.list_tools())}')"

Import Errors

# Install missing dependencies
cd mcp-server
pip install -r requirements.txt

# Or install python-dotenv
pip install python-dotenv
